Description

Technical Field

[0001] The invention relates to the technical field of security monitoring, in particular to a heating and demisting type security monitoring system. Background Art

[0002] Security monitoring is a comprehensive system that uses video, audio, infrared and other sensor equipment to perform real-time monitoring, alarm, recording, storage, remote transmission and other functions of the target. Its main purpose is to provide effective monitoring and early warning before or when a security incident occurs, helping people to discover and deal with problems in a timely manner.

[0003] During the use of monitoring devices, they are mostly installed by threaded connection. The bolted connection is not convenient for disassembly and maintenance of the monitoring. When the monitoring is damaged, its maintenance is not convenient. In order to overcome the above-mentioned defects, prior art 1 (publication number: CN219437086U, Chinese patent with publication date of 2023-07-28) is a video surveillance security device, including a surveillance camera body, and the top and both sides of the surveillance camera body are jointly installed with a fitting arc-shaped heat-conducting frame in a horizontal direction for sliding. An arc-shaped heat-conducting frame is fixed to one end of the arc-shaped heat-conducting frame close to the lens on the surveillance camera body, and the arc-shaped heat-conducting plate is located on the outside of the lens on the surveillance camera body. Springs in a vertical state are fixed to the middle of both ends of the outer surface of the top of the arc-shaped heat-conducting frame, and an arc-shaped protective frame is jointly fixed to the upper end of the spring. The arc-shaped protective frame and the arc-shaped heat-conducting frame are slidably connected in the vertical direction. During use, it is convenient to protect the surveillance camera body, avoid foreign objects falling from high altitude from hitting the surveillance camera body and causing damage to the surveillance camera body, and help to use the surveillance camera body normally.

[0004] There is also prior art 2 (publication number: CN219796768U, Chinese patent with publication date of 2023-10-03) a security monitoring device, which relates to the technical field of monitoring devices, including a mounting frame and a camera body rotatably arranged on the mounting frame, the mounting frame including a mounting seat and a support rod fixed on the mounting seat, the camera body rotatably arranged on the support rod; it also includes a fixed seat, the mounting seat is slidably arranged in the fixed seat, and a locking assembly for fixing the mounting seat is arranged on the mounting seat; the fixed seat is provided with a mounting groove adapted to the mounting seat, and a locking groove is provided in the mounting groove. The utility model can realize the rapid installation and disassembly of the mounting seat through the provided locking assembly, that is, when repairing the security monitoring device, the camera body can be disassembled without removing the bolts on the fixed seat. The design uses the provided locking block to achieve fixation during the installation of the mounting seat, which saves time and effort, is easy to operate, and facilitates the maintenance of the security monitoring device.

[0005] Although the existing technologies 1 and 2 can quickly install and protect the monitoring devices, the security monitoring itself cannot perform heating and defogging operations. In cold areas such as the north, the temperature is low in winter and the camera is prone to frost. In coastal areas, rainy areas or areas with heavy fog, the camera will be blocked by fog and lose its field of vision. Security monitoring that does not have heating and defogging operations has certain defects when used.

[0006] Therefore, we propose a heating and defogging security monitoring system to solve the above problems. Summary of the invention

The outer end of the auxiliary plate is threadedly connected to the inner end of the threaded rod, and an adjustment mechanism for shielding the auxiliary monitoring head is provided between the threaded rod and the end side of the shell.

[0009] Preferably, a slide groove is provided on the inner side of the limit ring, and a limit rod is fixedly connected between the inside of the slide groove and the inner side of the baffle, the side of the fixed bottom plate is nested and connected to the limit rod, and a return spring is fixedly connected between the fixed bottom plate and the inside of the slide groove, and the return spring is wound around the outer side of the limit rod; A fixing plate is fixedly connected inside the shell, and a winding wheel is fixedly connected at the inner center of the fixing plate. A pull rope is wound around the winding wheel, and the outer end of the pull rope is fixedly connected to the center of the fixed bottom plate.

[0010] Preferably, the fixed base plate forms a traction structure through a pull rope and a slide groove, and the fixed base plate forms a sliding structure through a return spring and the slide groove.

[0011] Preferably, the defogger mechanism comprises an air supply bag, the air supply bag is fixedly connected to the inner side of the baffle, a movable groove is provided inside the fixed seat, and a push bag is fixedly connected inside the movable groove, a rotating seat is provided at the center of the fixed seat, and a protruding end of the rotating seat is fixedly connected to the push bag, and a connecting hose is connected through the push bag and the air supply bag; The outer end of the rotating seat is fixedly connected with a heating plate, and the other end of the heating plate is fixedly connected with an auxiliary rod, and the auxiliary rod is nested and connected inside the shell.

[0012] Preferably, the air supply airbag is connected to the pushing airbag through a connecting hose, and the pushing airbag is arranged in an arc-shaped structure, and the pushing airbag is designed to be centrally symmetrical about the center point of the fixed base plate.

[0013] Preferably, the rotating seat forms a sliding structure by pushing the airbag and the movable groove, and the rotating seat and the heating plate form an integrated structure, and the heating plate is designed with an arc structure. At the same time, the inner side of the heating plate is in contact with the outer side of the monitoring head body, and the initial state of the heating plates on the upper and lower sides is vertical.

[0014] Preferably, the adjustment mechanism includes a protective plate, and the protective plate is arranged on the front side of the auxiliary monitoring head, a limiting groove is opened on the upper side of the front end of the shell, and a linkage plate is nested and connected inside the limiting groove, and a rotating rod is hinged on the inner side of the linkage plate, the outer side of the threaded rod is threadedly connected to an internal thread block, and the side of the internal thread block is hinged to the other end of the rotating rod.

[0016] Preferably, the rotating rod and the linkage plate form a rotating structure through the internal thread block, and the linkage plate forms a sliding structure through the rotating rod and the limiting groove.

[0017] Compared with the prior art, the present invention has the following beneficial effects: When the external environment causes the surface of the monitoring head body to be blocked by fog, the motor is started at this time, and the motor drives the winding wheel to rotate, thereby winding the pull rope. At this time, the pull rope will pull the fixed bottom plate set on the rear side of the monitoring head body, so that the fixed bottom plate slides toward the inside of the shell along the limit rod. At this time, the fixed bottom plate stably drives the monitoring head body to move into the shell, thereby preliminarily blocking the monitoring head body to prevent the fog from continuously blocking the monitoring head body. When the fixed bottom plate moves inward, it squeezes the air supply bag, so that the gas inside the air supply bag is transported to the inside of the push bag through the connecting hose. At this time, the push bag expands, thereby pushing the protrusion set on the side of the rotating seat, so that the rotating seat rotates along the movable groove. While the rotating seat rotates, it will synchronously drive the heating plate to erase along the monitoring head body. At the same time, the heat of the heating plate itself can dissipate the fog that blocks the monitoring head body, thereby reducing the possibility of fog blocking the monitoring field of the monitoring head body. At the same time, the monitoring head body enters the shell. At this time, when the heating plate is erasing, it will synchronously erase the dust on the upper side of the monitoring head body, and the erased dust will fall into the shell, reducing the possibility of dust falling and affecting other monitoring equipment. When the heating plate rotates, it will synchronously drive the auxiliary rod to rotate on the shell. The auxiliary rod can limit the heating plate, so that the heating plate can rotate stably, further improving the demisting efficiency; When the fixed bottom plate moves backward, it will synchronously drive the auxiliary plate to move backward along the outer side of the threaded rod. At this time, the threaded rod rotates under the action of the threaded connection with the auxiliary plate. When the threaded rod rotates, it will synchronously drive the internal thread block connected with it to move to one side of the shell. At this time, the internal thread block will drive the rotating rod to rotate and make the rotating rod push the linkage plate outward. Under the limiting action of the limiting groove, the linkage plate can stably drive the protective plate to move to both sides. At this time, the protective plate does not block the auxiliary monitoring head. The auxiliary monitoring head can perform monitoring operations during the process of eliminating fog on the monitoring head body, reducing the occurrence of incomplete and imperfect monitoring video. When the fog is eliminated, the motor is started to rotate in the opposite direction. At this time, the reel does not reel in the pull rope, and the fixed base plate is not pulled. Driven by the elastic force of the reset spring, the fixed base plate moves toward the side of the limit ring, thereby driving the monitoring head body to reset. At the same time, the protective plate blocks the auxiliary monitoring head, and the monitoring operation can continue through the monitoring head body. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Embodiment 1: Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 The technical solution shown in the figure, the present invention provides the following technical solution: a heating and demisting security monitoring, discloses a fixed bottom plate 10, through which the position of the monitoring head body 2 can be adjusted: A housing 1, a limit ring 5 is fixedly connected to the front side of the housing 1, a monitoring head body 2 is arranged inside the limit ring 5, and auxiliary monitoring heads 3 are fixedly connected to the upper and lower sides of the housing 1; A slide groove 11 is provided on the inner side of the limiting ring 5, and a limiting rod 12 is fixedly connected between the inner side of the slide groove 11 and the inner side of the baffle 14, the side of the fixed base plate 10 is nested and connected to the limiting rod 12, and a return spring 13 is fixedly connected between the fixed base plate 10 and the inner side of the slide groove 11, and the return spring 13 is wound around the outer side of the limiting rod 12; A fixed plate 9 is fixedly connected to the inside of the shell 1, and a winding wheel 18 is fixedly connected to the inner center of the fixed plate 9, and a pull rope 19 is wound around the winding wheel 18.

[0022] When the external environment causes the surface of the monitoring head body 2 to be blocked by fog, the motor 15 is started at this time, and the motor 15 drives the winding wheel 18 to rotate, thereby winding the pull rope 19. At this time, the pull rope 19 will pull the fixed base plate 10 set on the rear side of the monitoring head body 2, so that the fixed base plate 10 slides along the limit rod 12 to the inside of the shell 1. The fixed base plate 10 now stably drives the monitoring head body 2 to move to the inside of the shell 1, thereby preliminarily blocking the monitoring head body 2 to prevent the fog from continuously blocking the monitoring head body 2. When the fog is eliminated, the motor 15 is started to rotate in the opposite direction. At this time, the winding wheel 18 does not reel in the pull rope 19, and the fixed base plate 10 is not pulled. Driven by the elastic force of the reset spring 13, the fixed base plate 10 moves to the side of the limit ring 5, thereby driving the monitoring head body 2 to reset. At the same time, the protective plate 4 blocks the auxiliary monitoring head 3, and the monitoring operation can continue through the monitoring head body 2.

[0023] Embodiment 2: Figure 3 , Figure 4 , Figure 7 and Figure 8 The technical solution shown in the figure, the present invention provides the following technical solution: a heating and defogging security monitoring, disclosing a defogging mechanism, through which the obstructing fog can be erased: A fixed bottom plate 10 is fixedly connected to the inner side of the monitoring head body 2, a baffle 14 is fixedly connected to the inside of the housing 1, and a fixing seat 16 is fixedly connected to the side of the baffle 14, and a defogger mechanism is provided between the inner side of the fixing seat 16 and the baffle 14 to heat and erase the fog on the surface of the monitoring head body 2; The defogger mechanism includes an air supply bag 20, which is fixedly connected to the inner side of the baffle 14, a movable groove 22 is provided inside the fixed seat 16, and a push air bag 21 is fixedly connected inside the movable groove 22, a rotating seat 23 is provided at the center of the fixed seat 16, and the protruding end of the rotating seat 23 is fixedly connected to the push air bag 21, and a connecting hose 24 is connected between the push air bag 21 and the air supply bag 20, the outer end of the rotating seat 23 is fixedly connected to the heating plate 6, and the other end of the heating plate 6 is fixedly connected to the auxiliary rod 17, and the auxiliary rod 17 is fixedly connected to the auxiliary rod 17.

At the same time, the inner side of the heating plate 6 is in contact with the outer side of the monitoring head body 2, and the upper and lower heating plates 6 are initially in a vertical state.

[0024] When the fixed bottom plate 10 moves inward, it squeezes the air supply bag 20, so that the gas inside the air supply bag 20 is transported to the inside of the push bag 21 through the connecting hose 24. At this time, the push bag 21 expands, thereby pushing the protrusions set on the side of the rotating seat 23 to make the rotating seat 23 rotate along the movable groove 22. When the rotating seat 23 rotates (the rotating seats 23 on the left and right sides rotate in opposite directions), it will synchronously drive the heating plate 6 to erase along the monitoring head body 2. When the heating plate 6 rotates, it will synchronously drive the auxiliary rod 1 7 rotates on the shell 1, and the auxiliary rod 17 can limit the heating plate 6, so that the heating plate 6 can rotate stably, further improving the defogging efficiency. At the same time, the heat of the heating plate 6 itself can dissipate the fog that blocks the monitoring head body 2, thereby reducing the possibility that the fog blocks the monitoring field of view of the monitoring head body 2. At the same time, during the rotation of the heating plate 6, the dust stuck on the surface of the monitoring head body 2 can be wiped off, and the wiped dust falls into the inside of the shell 1, reducing the possibility of dust falling directly and polluting other monitoring equipment.
